The MX43 is an 8-channel analog gas detection controller designed for monitoring gases present in the atmosphere (explosive, toxic or asphyxiating). It is also engineerd to manage any 4-20 mA or all-or-nothing signal.

Thanks to its digital technology, the MX43 can be connected up to 32 detectors on its 8 channels, reducing wiring costs.

Very easy configuration and operation are performed with a keyboard placed closed to the large backlit screen.

Thanks to many smart options (flashing light + on-bord siren, internal battery backup, logical input module, measurement report module…) the MX43 gas detection controller is technically and cost-effectively the ideal solution for many gas detection applications.
